To all whom it may concern:

Be it known that I, PAUL M.. BEARD, a

city of St. Louis, State of Missouri, have invented a certain new anduseful Improvement in Car End Construction, of which the following is afull, clear, and exact descriptron, such as-will enable others. skilledin the art to which it appertains to make and use the same, referencebeing had to theaccompanying drawings, forming part of thisspecification. 7 fMyi-invention relates to railway car-construction, andpertains particularly to the construction of sheet metal ends for boxcars. The principal object of my present invention is to provide a.construction wherein the end is made up of corrugated or ribbed sectionsof sheet metal. which are secured together in such fashion as to form abeam whose members are formed by; portions of the sheet metal, and whichare so constructed as. to insure them against failure under serviceconditions. I

Another object of my invention is to pro: vide an improved means forsecuring ends to cars, the object of which is'to facilitate attachmentand detachment in construction and repair. I

A further object of my. invention is to as to reinforce the framingmembers to which it may be attached in the car superstructure.

Other objects of my invention will be obviousor pointed out hereinafter.

Two forms of my invention are illustrated in the accompanying drawingswherein Figure 1 is a front elevation of a car end embodying myinvention; Fig. 2 is an elevational section thereof taken approximatelyon line22 of Fig. 1; Fig. 3 is a detail showing a cross section at thecorner of a car substantially on line 33 of Fig. 1, andincluding-a'portion ofthe girth strip in section at a 'sideor transompost. Fig. 4' is a detail illustrating a modification; Fig. 5 is adetail illustrating a feature of the attachin means.

: n the car end illustrated in the drawings, lrepresents an uppersection and 2 represents'a lower section, both of sheet metal, whichhave their adjacent edges flanged out- Wardlyand in L-form, asillustrated in .Fig.

2, as departing portions 4 and joining portions 5. The joining portions5 are overresiding at the tension member disposed in a plane removedfrom the-major plane of the sections. Disposed transversely of the beamare corrugations 6 which may be faded or merged into .the departingportions 4, or may terminate ad a'cent thereto. These corrugations 6operate to stiffen the sections 1 and 2 transversely, and to transmitthe stiffening influence of the beam across them. A connecting strip 7is disposed against the inner faces of the sections and connectedthereto at the inward sides of the departing portionset, thereby tyingthe sections together approximately in their'major plane across theoutwardly pressed marginal portions. This connecting strip extends theentire length of the end wall, and preferably is attached to the cornerposts, together with the side flanges 8 of the sections. This connectingstrip forms a compression member Whichcooperates with the tension memberformed by the overlapped and connected portions 5 to provide a beamextending longitudinally ofthe sections across the car end at thejunction of the sections, and operating to greatly strengthen andstiffen the end against various service shocks.

lapped and secured together, and form a I refer to the tie strip 7 asthe compression member, and the member formed by the portions 5 as thetension member of the beam, for the reason that the strip 7 is normallyput under some slight compression when the end is aflixed to the can-andthe major service shocks, which are the stresses imparted to the end byshifting of the cargo thereagfainst, also place the connecting strip 7under compression and the member formed by the portions 5 under tension.Due to the fact that the member 7 is frequently, if not normally, underappreciable compression, which would render it liable to failure ifstarted by a' 'ocal strain, I provide means for stiffening andreinforcing said connecting strip against such failure. To thiseffailure of the beam from a local strainv therein. Said corrugations 9also provide the sections.

As illustrated in Fig. 2, the lower margin of section 2 is normallyriveted to the upper portion of the car end sill 10. In service itfrequently occurs that violent thrusts against the end will bend the webof the end sill, throwing the upper portion of the sill outwardly. Asameans for further resisting such thrusts and taking a portion thereoffrom the end sill, I provide the corrugations 11 pressed inwardly at thecorner where the margin of the section is flanged rearwardly to providethe bottom flange 12. These corrugations form connecting gussets betweenthe vertical wall of the section and the flange, stiffening the metalacross the corner so as to prevent its bending on the corner and on theline of the fastenings which connect it to the end sill. The flange12being secured in position to the floor framing members illustrated indotted lines in Fig. 2, the construction will operate to relieve the endsill of an appreciable amount of bending stress imparted by loadthrusts.

My improved arrangement for connecting the sections to the carsuperstructure at the ends of the beam member, is illustrated in Figs. 3and 5. The corner posts 14 and side posts 15 are slotted for the passageof a metal girth strip 16 which is seated therein, extending back fromthe end as far as desired. This girth strip is bolted to the posts andhas bolted to it at either side furring strips 17. These strips providematerial to which the lining 18 and sheathing 19 may be nailed. The endsof these girth strips -project beyond the corner posts and are turnedover as is illustrated at 20 in Fig. 3. At suitable points to receivethese projecting 'ends, the members 5 of the sections are provided withapertures 21 adapted to permit the passage therethrough of theturned-over portions. When the end is applied to the car, the sideflanges 8 are bolted to the corner posts, the ends of the strips 16projecting through the apertures 21. A keeper 22 having a pocket for thereception of the bentover end 20 is then placed in engagement with saidbent-over end and is riveted or bolted to the members 5. Thisconstruction forms a very secure attachment of the sections to the carsuperstructure immediately at the ends of the beam member. At such timesas it becomes necessary to remove the end for repairs, the sections arereadily freed from this attachment by simply detaching the keeper 22,which will permit the with drawal of the sections from the projectingends of the girth strips.

In the modification illustrated in' Fig. 4, the tension member is formedentirely by the portions 4.
